GAS BURNER Filed April 29. 1929 ATTORNEY.

Patented Nov. 24, 1931 UNITED STATES PATENT OFFECE BEN G. JENNINGS, OF DALLAS, TEXAS, ASSIGNOR OF ONE-HALF TO MABEL R. SPELL- MAN, DALLAS, TEXAS GAS BURNER Application filed April 29,

This invention refers to new and useful improvements in gas burners and the object of the invention is the production of a gas burner cap to provide an even and uniform flame in the burner.

The new and improved cap is so constructed that it can be placed over the ordinary gas burner and in addition to providing a uniform flame eliminates soot, smoke and is sanitary and safe. The cap also enables the burner to be operated with less gas.

In the drawings accompanying this specification:

Figure 1 is a top plan view of an ordinary gas burner, gas cock and air regulator valve and illustrating an embodiment of the invention.

Figure 2 is a top plan view of the burner cap by itself.

Figure 3 is a bottom vien of the burner cap, and

Figure 4 is a cross-sectional view of the burner cap, on line lt of Figure 2, the gas burner shown in broken lines.

Referring to the drawings more in detail, 1 denotes a gas feed pipe on a gas range, 2 the gas cock and 3 the air regulator valve. Connecting the valve with the burner 7 is the regular pipe 5. The invention consists of a cap, circular in form, of a hollow interior. The cap has a central opening 8, formed by the annular walls of a fine 9 and a top portion 6. The 3 top is provided with spaced openings 10, and

through the flue the gas flows upward from the burner 7.

The cap is constructed for use on an ordinary gas burner of standard type.

The top 6 as will be apparent from Figure 4, is formed integrally with the walls 11 and 12, the upper portion 11 being thicker than the lower portion 12. This is for the purpose of enabling the cap to seat on the an- 45 nular shoulder 14 of the burner, the lower wall 12 embracing the burner. The lower rim of the flue is also provided with spaced projections 15 so that the gas may pass freely between the top of the burner and the flue.

When the cap is in operative position, the

1929. Serial No. 359,016.

top edge of the flue is on a level with the top of the gas range.

When the cap is in the operative positions shown in Figures 1 and a, the valve 3 is set for the required amount of gas. Owing to the construction of the cap, less gas will be necessary, because the gas is entirely consmned. This perfect combustion is brought about by the air vacuum created within the cap, caused by the gas filling completely the 0 entire inner surface area of the cap. The top 6 limits the upward flow of the gas and its me, causing a diffusion of the combustible uniformly in the cap. The provision of the flue creates the proper draft, and the result is an intense heat on less amount of gas, no smoke or soot being present. The air mingles with the gas from beneath the burner and cap only.

Obviously the cap is capable of modifications to suit different types of burners and may be further modified to come within the meaning of the following claim.

\Vhat is claimed as new is:

A gas burner cap comprising a substantially vertical cylindrical outer wall thicker at its upper portion than at the lower portion, a shoulder on the interior of the wall to seat the cap on a gas burner, a central flue substantially cylindrical in form having spaced lugs on the lower edge thereof for seating on the burner, and a substantially flat web portion connecting the top of said outer wall with said cylindrical flue, said web portion having spaced perforations therein, said cylindrical flue extending a substantial distance above the level of said flat web portion.

In testimony whereof I afiix my signature.

BEN G. JENNINGS.
